Sublimation Paper Coating Chemicals CMC Sodium CMC 

Sublimation Paper Coating Chemicals CMC Sodium CMC When a low viscosity Sodium Carboxymethyl Cellulose SCMC is used in the coating test of coated whiteboard, it is found that adding Sodium CMC to the coating can greatly improve the water retention performance of the coating and control the rheology of the coating. In the low shear rate range (10-1 ~ 102s-1), the coating containing CMC Chemical is a shear thinning fluid, and the viscosity decreases by nearly half. In order to adjust and control the rheology of the paint, the amount of CMC Powder should be limited to 0.5 ~ 1.0 parts /100 parts of the pigment, and the surface coating is slightly lower than the bottom coating. In addition,Papermaking Grade CMC also plays a great role in improving the optical properties and printing properties of coated whiteboard.
